FIG. 1 is a block diagram of a power distribution unit adopting an IP address display device according to an embodiment of the present invention. As shown in FIG. 1, the power distribution unit 100 comprises two conductors 102, a plurality of switch units 104, a plurality of sensing units 106, a plurality of outlets 108, an AC-DC conversion circuit 110, an IP address display device 112, a memory unit 120 and an input interface 122, wherein the IP address display device 112 comprises a control circuit 114, a display interface 116, and a communication interface 118.

One of the conductors 102 is used to electrically couple an AC power source L, and the other conductor 102 is used to electrically couple a neutral line N. Each outlet 108 is electrically coupled to the neutral line N through one of the conductors 102, and each outlet 108 is electrically coupled to the AC power source L sequentially through one of the sensing units 106, one of the switch units 104 and the other conductor 102. The coupling manners of the outlets 108 described above are not used to limit the present invention. For example, each outlet 108 can be electrically coupled to the AC power source L through one of the conductors 102, and each outlet 108 can be electrically coupled to the neutral line N sequentially through one of the sensing units 106, one of the switch units 104 and the other conductor 102.

In addition, an input of the AC-DC conversion circuit 110 is electrically coupled to the two conductors 102. As for the control circuit 114, it is electrically coupled with an output of the AC-DC conversion circuit 110, the memory unit 120, the input interface 122, the display interface 116, the communication interface 118, each switch t 104 and each sensing unit 106. Each sensing unit 106 is used to measure current and accordingly provide a sensing result (as shown by D1 to DN, respectively, where N is a natural number). In this way, the control circuit 114 can calculate a corresponding loading according to each sensing result. The control circuit 114 is also used to output control signals C1 to CN, where N is a natural number, so as to control the on/off state of the switch units 104, respectively. In addition, the above-mentioned input interface 122 is used for a user to operate the display interface 116, and is used for the user to directly input a control command to the control circuit 114. Furthermore, the above-mentioned communication interface 118 can be a wired communication interface or a wireless communication interface, and the present invention is not limited thereto.

FIG. 2 is a flowchart of an operation of an IP address display device according to an embodiment of the present invention. Referring to FIGS. 2 and 1, in this embodiment, when the power distribution unit 100 is electrically coupled to the AC power source L and the neutral line N, the AC-DC conversion circuit 110 provides operation power to the control circuit 114, so that the control circuit 114 can enable the display interface 116 to be in normal operation (as shown in step S202). At this time, the image displayed by the display interface 116 can be, for example, the image as shown in FIG. 3. FIG. 3 shows the display interface displaying a main menu.

Next, the control circuit 114 determines whether a network has been connected through the communication interface 118 (as shown in step S204). In step S204, when the determination result is no, the control circuit 114 returns to step S202. On the other hand, when the determination result is yes, the control circuit 114 further determines whether an IP address allocated by a DHCP server has been obtained through the communication interface 118 (as shown in step S206).

In step S206, when the determination result is no, the control circuit 114 returns to step S202. On the other hand, when the determination result is yes, the control circuit 114 automatically displays the obtained IP address by the display interface 116 for a preset time (as shown in step S208). FIG. 4 shows the delay interface displaying the obtained IP address. After step S208 is performed, the control circuit 114 returns to step S202. It is worth mentioning that, in this embodiment, the control circuit 114 can store the obtained IP address in an internal register thereof (not shown), or store the obtained IP address in the memory unit 120 for accessing when needed.

From the above description, it can be seen that when the IP address display device 112 determines that an IP address allocated by a DHCP server has been obtained, the IP address display device 112 automatically displays the obtained IP address, so that a user can quickly obtain the IP address of the power distribution unit 100 for remote management.

In addition, for flexibility in operations, the control circuit 114 can receive a control command transmitted by a user through the input interface 122 or the communication interface 118, and adjust the length of the preset time accordingly, or determine whether to enable the function of automatically displaying the obtained IP address accordingly. It is worth mentioning that although in this embodiment the power distribution unit 100 adopts a plurality of switch units 104, a plurality of sensing units 106, a memory unit 120, and an input interface 122, however, whether to adopt these components in the power distribution unit 100 can be determined based on actual design requirements.

FIG. 5 is a block diagram of an uninterruptible power system adopting an IP address display device according to an embodiment of the present invention. As shown in FIG. 5, the uninterruptible power system 500 comprises a filtering unit 502, a switch unit 504, a first voltage conversion circuit 506, a second voltage conversion circuit 508, a switch unit 510, a filtering unit 512, a charging circuit 514, a battery 516, a sensing circuit 518, an IP address display device 520, a memory unit 528, an input interface 530, and a bypass path 532, wherein the IP address display device 520 comprises a control circuit 522, a display interface 524, and a communication interface 526.

The switch unit 504 is electrically coupled to the battery 516 and one terminal of the bypass path 532, and is electrically coupled to AC mains (not shown) through the filtering unit 502. The charging circuit 514 is electrically coupled to the battery 516 and an output of the filtering unit 502, and is used for charging the battery 516. An input terminal of the first voltage conversion circuit 506 is electrically coupled to the switch unit 504. An input terminal of the second voltage conversion circuit 508 is electrically coupled to an output terminal of the first voltage conversion circuit 506. The switch unit 510 is electrically coupled to an output of the second voltage conversion circuit 508 and the other terminal of the bypass path 532, and is electrically coupled to an output 540 of the uninterruptible power system 500 through the filtering unit 512, wherein the output 540 of the uninterruptible power system 500 is used for electrically coupling a back-end device (not shown). The sensing circuit 518 is electrically coupled to the AC mains, the battery 516, and the output 540 of the uninterruptible power system 500, so as to measure the power state of the AC mains, the battery 516, and the output 540 of the uninterruptible power system 500.

As for the control circuit 522, it is electrically coupled to the switch unit 504, the first voltage conversion circuit 506, the second voltage conversion circuit 508, the switch unit 510, the charging circuit 514, the sensing circuit 518, the display interface 524, the communication interface 526, the memory unit 528, and the input interface 530, so as to control the operation of these components. For example, the control circuit 522 can control the first voltage conversion circuit 506 to perform a DC-DC voltage conversion operation or an AC-DC voltage conversion operation, and control the second voltage conversion circuit 108 to perform a DC-AC voltage conversion operation. In addition, the control circuit 522 can control the switch unit 504 to transfer the output of the filtering unit 502 to the first voltage conversion circuit 506 or the bypass path 532, or control the switch unit 504 to transfer the output of the battery 516 to the first voltage conversion circuit 506. Further, the control circuit 522 can control the switch unit 510 to transfer the output of the second voltage conversion circuit 508 to the filtering unit 512, or control the switch unit 510 to electrically couple the bypass path 532 to the filtering unit 512.

In addition, the above-mentioned input interface 530 is used for a user to operate the display interface 524, or for the user to directly input a control command to the control circuit 522. Furthermore, the above-mentioned communication interface 526 can be a wired communication interface or a wireless communication interface, and the present invention is not limited thereto.

Referring to FIGS. 5 and 2, in this embodiment, when the uninterruptible power system 500 is electrically coupled to the AC mains, the operation power supplying circuit (not shown) in the uninterruptible power system 500 provides operation power to the control circuit 522, so that the control circuit 522 can enable the display interface 524 to be in normal operation (as shown in step S202). At this time, the image displayed by the display interface 524 can be, for example, the image as shown in FIG. 3. FIG. 3 shows the display interface displaying a main menu.

Next, the control circuit 522 determines whether a network has been connected through the communication interface 526 (as shown in step S204). In step S204, when the determination result is no, the control circuit 522 returns to step S202. On the other hand, when the determination result is yes, the control circuit 522 further determines whether an IP address allocated by a DHCP server has been obtained through the communication interface 526 (as shown in step S206).

In step S206, when the determination result is no, the control circuit 522 returns to step S202. On the other hand, when the determination result is yes, the control circuit 522 automatically displays the obtained IP address by the display interface 524 for a preset time (as shown in step S208). FIG. 4 shows the display interface displaying the obtained IP address. After step S208 is performed, the control circuit 522 returns to step S202. It is worth mentioning that, in this embodiment, the control circuit 522 can store the obtained IP address in an internal register thereof (not shown), or store the obtained IP address in the memory unit 528 for accessing when needed.

From the above description, it can be seen that when the IP address display device 520 determines that an IP address allocated by a DHCP server has been obtained, the IP address display device 520 automatically displays the obtained IP address, so that a user can quickly obtain the IP address of the uninterruptible power system 500 for remote management.

In addition, for flexibility in operations, the control circuit 522 can receive a control command transmitted by a user through the input interface 530 or the communication interface 526, and adjust the length of the preset time accordingly, or determine whether to enable the function of automatically displaying the obtained IP address accordingly. It is worth mentioning that although in this embodiment the uninterruptible power system 500 adopts the filtering unit 502, the filtering unit 512, the memory unit 528, and the input interface 530, however, whether to adopt these components in the uninterruptible power system 500 can be determined based on actual design requirements. Furthermore, although FIG. 5 exemplifies a type of the uninterruptible power systems, this is not intended to limit the present invention. Those skilled in the art should know that the IP address display device 520 of the present invention can be applied to all types of the uninterruptible power systems such as off-line type, on-line type, and line interactive type.

In summary, when the IP address display device determines that an IP address allocated by a DHCP server has been obtained, the IP address display device automatically displays the obtained IP address, so that a user can quickly obtain the IP address of the power device (e.g., power distribution unit, uninterruptible power system) adopting the IP address display device for remote management.
